DIVERSIFIKASI DAN BRANDING PRODUK OLAHAN RAMBUTAN DALAM MENINGKATKAN KETAHANAN PANGAN DAN EKONOMI MASYARAKAT DESA KALISALAK

Komoditas rambutan menjadi salah satu komoditas yang memiliki produktivitas tinggi di Desa Kalisalak, Kecamatan Batang, Kabupaten Batang. Badan Pusat Statistik (2021) mencatat produksi buah rambutan terutama di Kabupaten Batang mengalami peningkatan yang signifikan di tahun 2020. Pada 2019 produksi buah rambutan mencapai 26.910 kg dan 43.210 ton pada 2020 atau meningkat sebanyak 60,5% dalam setahun. Akan tetapi, harga yang rendah saat musim panen menjadikan rambutan tidak memiliki keunggulan ekonomi dibandingkan komoditas buah lain. Disisi lain, permasalahan limbah kulit rambutan yang terbuang dapat berdampak terhadap lingkungan. Oleh karena itu, pengabdian ini dilakukan dengan memberikan solusi inovatif dengan diversifikasi produk olahan rambutan menjadi asinan daging buah dan minuman seduh kulit rambutan. Tim pengabdian melakukan workshop dan pelatihan untuk membuat produk olahan rambutan sekaligus meningkatkan ketahanan pangan dan ekonomi masyarakat Desa Kalisalak. Tim pengabdian juga menginisiasi branding dan pemasaran produk melalui Pusat Belanja sahabat Lingkungan Kalisalak di Desa Kalisalak. Pengabdian ini diharapkan dapat meningkatkan ketahanan pangan dan kesejahteraan ekonomi masyarakat

Relativistic model of hidden bottom tetraquarks

The relativistic model of the ground state and excited heavy tetraquarks with hidden bottom is formulated within the diquark-antidiquark picture. The diquark structure is taken into account by calculating the diquark-gluon vertex in terms of the diquark wave functions. Predictions for the masses of bottom counterparts to the charm tetraquark candidates are given.Comment: 6 page

Medusaegraptus (Chlorophyta, Dasycladales) from the Pridolian to middle Lochkovian Indian Point Formation, New Brunswick, Canada

Carbonaceous compressions from the Pridolian to middle Lochkovian Indian Point Formation in the Flatlands area of New Brunswick comprising a central axis with irregularly arranged unbranched appendages are assigned to Medusaegraptusmirabilis. This is the first report of intact thalli of this noncalcified macroalgal taxon from a locality outside of western New York. The biotic composition, stratigraphic context, and sedimentology of this occurrence suggest a shallow-marine depositional setting roughly comparable to that for the type material of Medusaegraptus mirabilis from Gasport, New York.RÉSUMÉLes fossiles carbonés comprimés de la formation d’Indian Point, située dans la région de Flatlands du Nouveau-Brunswick et qui date du Pridolien au Lochkovien moyen, sont attribués àMedusaegraptus mirabilis; ils présentent un axe central avec des appendices non ramifiés et disposés de façon irrégulière. C’est la première fois qu’on signale la présence de thalles intacts de ce taxon de macroalgues non calcifiées dans une localité ailleurs que dans l’ouest de l’État de New York. La composition biotique, le contexte stratigraphique et les données sédimentologiques permettent de penser à un dépôt marin peu profond à peu près comparable à ce qu’on trouve dans le cas de Medusaegraptus mirabilis de Gasport, dans l’État de New York.[Traduit par la redaction] 

Performance bounds for expander-based compressed sensing in Poisson noise

This paper provides performance bounds for compressed sensing in the presence of Poisson noise using expander graphs. The Poisson noise model is appropriate for a variety of applications, including low-light imaging and digital streaming, where the signal-independent and/or bounded noise models used in the compressed sensing literature are no longer applicable. In this paper, we develop a novel sensing paradigm based on expander graphs and propose a MAP algorithm for recovering sparse or compressible signals from Poisson observations. The geometry of the expander graphs and the positivity of the corresponding sensing matrices play a crucial role in establishing the bounds on the signal reconstruction error of the proposed algorithm. We support our results with experimental demonstrations of reconstructing average packet arrival rates and instantaneous packet counts at a router in a communication network, where the arrivals of packets in each flow follow a Poisson process.Comment: revised version; accepted to IEEE Transactions on Signal Processin
